[VHFcontesting] question

DirectTV dishes make pretty good 10 GHz dishes, check W1GHZ's website.

RG6 will handle several hundred watts at 2m, more at 6, less at 70cm. If you are using it to feed a single frequency antenna, you can make a transformer to go from 75 down to 50 ohms at each end. Since directTV uses block downconverters built in to the feeds and these are in the 1 GHz range, most of the RG6 that is used is pretty good stuff and fairly low loss. If you are going to use it for 2m and 70cm, the same transformer should work since it would be one quarterwave on 2 and three quarter wave on 70cm.

I, too, ditched DirecTV a while ago, and I've been wondering the same sorts of 

things. My DirecTV dish is mounted on an eave.



Wouldn't it be neat to have a 2m vertical there? I think it's wise to leave 

the coax in place. Is it 75 ohm?  I'll bet there's some way to use it for 

receive at least, but I wonder just what sort of power that cable could 

stand.



If nothing else, you now have a nice high dipole midpoint, even if you have to 

run some coax to it.



Also wouldn't it be neat to use that mounting bracket for solar panels?
